A florney Patented June 15, 1937 UNITED STATES PATENT OFFICE DEVICE FOR SUPPLYING MOISTURE TO MOTORS 1 Claim.

This invention relates to a-device for supplying moisture to internal combustion motors, the general object of the invention being to provide means for connecting the inlet manifold to the 5 radiator so that moist air will be drawn into the manifold, with means for preventing too much of the moisture to be carried into the manifold.

This invention also consists in certain other features of construction and in the combination 10 and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, refer- 5 ence will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:--

Figure 1 is a sectional view of the device.

Figure 2 is a detail section on the line 2-2 of Figure 1 looking downwardly.

In this drawing the numeral I indicates the receptacle which is supported in any suitable manner adjacent the motor and which has its top 25 connected with the inlet of the manifold by a pipe 2. A bowl 3 is connected to the top of the receptacle and surrounds the outlet to the tube 2, the lower part of the bowl having the perforations 4 therein for admitting air from the recep- 30 tacle into the bowl from which it passes through the tube 2 to the manifold. A downwardly tapered member 5 depends from the top of the receptacle and has its upper part surrounding the bowl, and a substantially cup-shaped bafile 6 is 35 located in the member 5 below the bowl and has the recesses I in its side for the passage of air.

The lower part of the member 5 is open, and above the open end said member is provided with the perforations 8, and a pipe 9 extends through 40 the bottom of the receptacle and passes up through the lower portion of the member 5 to a point above the upper ends of the tubes I which pass through the holes at the bottom of the receptacle and are located exteriorly of the lower 45 part of the member 5. These tubes admitting air into the receptacle from below the bottom thereof.

A hose I I connects the lower end of the tube 9 with one side of a cup-shaped member I2 the 50 bottom of which is provided with perforations I3, and a pad I4 of felt or the like is located in the lower part of this member I2 and is held in position by a compressed part I of the cover I6 of the member I2. This depressed part is spaced from the walls of the member I2 so that the moist air flowing into the member I2 from the radiator through the pipe I'I must pass around the part I5 to reach the outlet I8 which 60 is connected with the hose II.

An opening I9 is, located in the top of the receptacle I and is enclosed by a cage 20 which contains a ball valve 2i which closes the opening I9 under the action of gravity but which will open said opening if the receptacle I is turned over, this arrangement being used when the device is placed on an aeroplane. When the vehicle is in upright position the valve 2| will close the opening I9 and thus prevent the entrance of air into the receptacle. I

The lower part of the receptacle I contains water which, of course, can never pass above the level shown by the dotted line 22.

When the motor is in operation moist air will be drawn from the radiator through the member I 2 which acts to take out some of the moisture from the air when the air will pass through the hose II and the pipe 9 into the member 5 and will also pass upwardly by the baffle 6 which prevents too much moisture passing from the device, and then the air will pass into the bowl 3 and through the pipe 2 to the inlet manifold so that this moist air will enter the cylinder and promote the efiiciency of the motor.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.

What is claimed is:

The herein described device for supplying moisture to motors, comprising essentially an upright receptacle, an outlet in the top of the receptacle, a bowl pendent from the top of the receptacle and disposedtherein and surrounding said outlet opening and having a closed lower end and a perforated side Wall, a shell pendent in the receptacle from the top thereof and having an apertured lower portion terminating adjacent to the bottom of the receptacle, an upright fluid inlet pipe extending upwardly through the bottom of the receptacle and terminating in said shell at a point spaced above the apertured portion thereof, a cup-shaped bafiie in the shell and supported by the side thereof and having its peripheral portion engaging the shell side and equipped with spaced indentations defining bypasses between it and the shell side, upstanding tubes in the receptacle and on opposite sides of the lower portion of the shell and extending through apertures in the bottom of the receptacle and terminating in a plane below that of the upper end of the fluid inlet pipe and at a point above the apertured portion of the shell.
